DBA DBA456S Street Series T2 Slotted Brake Disc Rotor

The DBA DBA456S Street Series T2 Slotted Brake Disc is a direct OEM-replacement rotor engineered for drivers seeking a meaningful performance upgrade over a standard factory disc. Sold individually, this front slotted brake rotor is manufactured by Disc Brakes Australia (DBA), a globally recognized leader in brake rotor quality and safety with over 30 years of engineering expertise.

Patented T2 Slot Design:

• Features precise, CNC-machined bi-symmetrical curved slots that dampen vibration harmonics for a quieter, more responsive brake pedal feel
• Slots provide multiple exit points for friction dust and gases to escape, enhancing pad bite and braking consistency
• Promotes even pad wear across the full contact surface, minimizing glazing and preventing lip formation that causes squealing and vibration
• Bi-directional design allows universal left/right fitment — no need for separate driver and passenger side rotors

Kangaroo Paw Vane Technology:

• DBA's patented internal vane design features 144 diamond and teardrop-shaped pillars between rotor faces
• Provides up to 20% better heat dissipation compared to conventional rotor designs
• Increases dimensional stability and reduces heat warpage for extended rotor life
• Centre-split core castings further improve heat transfer and thermal efficiency

Precision Manufacturing:

• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation, reducing the potential for pad knock and premature wear
• Surface machined to micron-level smoothness for optimal pad bed-in and long-term performance
• Sized to exact OEM dimensions for a bolt-on replacement with no modifications required

Warranty: DBA backs this rotor with a 12-month / 12,000-mile limited warranty against defects in materials and workmanship from the date of purchase.

The DBA456S Street Series T2 is the ideal upgrade for drivers who want improved stopping performance and durability over a stock brake disc without stepping into a full motorsport-level rotor. Part number suffix "S" denotes the T2 slot design within the DBA Street Series lineup.
